Man you sound like the user Imasockpuppet from the forum which doesn't exist anymore. Anyway, the Project MKUltra began in the early 1950s and and was officially stopped in 1973. There were many atrocities around the world at the time and most of the people weren't aware of that. But now we are living in a different situation: if something like that happens a Snowden would tell us. )
not sure if you think live/online beheadings and stuff like that is much different/better then the happenings of 50-100 years ago.
the story of the book itself didnt change much, it just got a new cover.
Live/online beheadings and things like that are not approved by any government or any authority that can rightly claim to be the legitimate central government of a state in current times. So the book has changed a bit in a good way.
look at the the arabian states like saudi arabia and what punishment they use.
look the north koreas prison camps. there are still a lot of totalitarian states existing today.
it is not just isis and al-qaeda (which btw. are government produced problems) that commit atrocities
